Respin Sparky + LAMP + Joomla

[yadbash]

I have been researching Plymouth and  grub splash image file locations in Sparky but, can't find one.

Where is the 2nd Sparky Splash image that is between grub and login screen splash ? or the .conf file that has path listed ?

Starting Next Month, I will have  15 months of Free time on my hands  to create a Respin Sparky 4.9  + LAMP + Joomla iso for USB Thumb drive so people can boot and learn both Sparkylinux & Joomla 3.9. All will be localhost and they don't need internet to learn.

(will include necessary disclaimer not developer issued version of Sparky
